scripts: twister: Elevate Status Error

Status errors previously logged an error, but didn't fail the running test.
This commit changes that
 and introduces a new StatusAttributeError to use there.

One test is modified so it follows proper status form.
One test for the new error has been added.

Status errors now will properly mark the Instance as ERROR
and not run TestCases as SKIP.
This necessitated some code layout changes in runner.py
